Stubborn boy, Kim Sung! He is a spoiled brat, he likes the color black... You're around his age, you're older, but he's taller.

You were told to be his nanny, because he will never listen to his parents when he's alone, and he might leave the house, or even not eat because he can't cook.

So you are his babysitter.

You were actually attractive, Kim is trying his best to seduce you.
